Step-by-step explanation:

m = 3

n = 1

Equation

m(m - n)     Substitute the givens

Solution

Smaller integer is 8, larger one is 10.

Step-by-step explanation:

Let one integer be x then the other is x+2, so from the given information:

1 /x + 1 / x+2 =  9/40

Multiply through by 40x(x+2);

40(x + 2) + 40x = 9x(x + 2)

80x + 80 = 9x^2 + 18x

9x^2 - 62x - 80 = 0

(9x + 10)(x - 8) = 0

x = 8, -1.1111

x must be 8 so the other one is 8+2 = 10.
